Ex-Resorts World Vegas Compliance Chief Sues After Firing

Resorts World Las Vegas lawsuit: why this case matters

A former compliance director at Resorts World Las Vegas, Preston Banks, has filed a lawsuit against the casino after being fired. His claim is straightforward but serious: he says he lost his job after raising alarms about suspicious gamblers and possible illegal financial activity.

For poker and casino players, this is more than an internal employment dispute. It touches on the core of how modern gaming properties protect themselves: AML compliance, source-of-funds checks, marker controls, and the way management responds when red flags appear.

In Las Vegas, where a casino’s reputation is built on trust, licensing, and regulatory discipline, a case like this can ripple far beyond one employee. It can affect how operators train staff, how they review player credit, and how aggressively they react to unusual betting patterns.

Suspicious gamblers, casino credit, and the first red flags

Banks began working at Resorts World in September 2022. Later that year, according to the lawsuit, he discovered suspicious activity involving a group of international gamblers from Argentina.

The key issue was not simply that the players were active or betting big. The complaint says the source of funds could not be verified because the businesses listed on their casino credit applications did not exist or could not be located.

That is a major compliance problem. When a casino extends credit, it is effectively trusting that a player’s financial profile is real and that the money is traceable. If that chain cannot be verified, the property is exposed to regulatory risk and potential laundering concerns.

In 2023, Banks reportedly asked supervisors and the property’s anti-money laundering committee to ban third-party marker payments by three customers. According to the suit, management accepted that recommendation. That suggests the casino understood the seriousness of the issue, at least at that stage.

The case widened: dozens of gamblers and more than 50 reports

The lawsuit says the scheme expanded in the following year to as many as 60 to 150 gamblers. The group allegedly included players from Mexico, Paraguay, Uruguay, Italy, and Spain. The complaint points to betting behavior that should have triggered money-laundering concerns.

The lawsuit says Resorts World’s own records described suspicious activity including:

• unverified source of funds;
• credit fraud;
• repeated third-party marker payments;
• coordinated or “coached” wagering;
• chip passing;
• chip walking;
• bankrolling;
• minimal gaming;
• offsetting bets;
• bill-stuffing.

By September 2024, staff had filed more than 50 suspicious activity reports. Banks says that was required under the Bank Secrecy Act. In other words, the warning signs were not isolated; they had become a pattern.

That is one of the most important takeaways for casino professionals. Once suspicious activity becomes repetitive, the issue is no longer whether a single player is unusual. It becomes whether the property’s controls are strong enough to detect and stop a broader network.

Termination, internal conflict, and the whistleblower response

After Banks filed a detailed report on the scheme, the property banned 28 people. Resorts World also referred those accounts to the Clark County District Attorney’s Office for collection of about $12 million in unpaid casino credit.

Later that same month, Banks was fired.

His attorneys argue that the timing is critical: he says he helped uncover the scheme and kept warning management, yet he was the one removed. The complaint says Banks told management that he had detected the scheme and objected to the casino firing the person who identified it. In the filing, he is quoted as saying, “I detected it, you’re killing the author.” HR Director Bob Napierala allegedly replied that the termination decision came from “the c-suite.”

For readers who follow poker clubs, the broader lesson is familiar: the most successful gaming businesses are not just the ones with volume, but the ones with discipline. Compliance, audit trails, and internal escalation are as important as promotions, traffic, or a packed room.

Whistleblower complaints and the regulators involved

In December, Banks filed a whistleblower-retaliation complaint with the U.S. Department of Labor’s Occupational Safety and Health Administration under the Anti-Money Laundering Act of 2020.

He also submitted similar complaints to the Treasury Department’s Financial Crimes Enforcement Network and to the Justice Department’s Corporate Whistleblower Awards Pilot Program. That matters because it shows the dispute is now moving through multiple regulatory channels, not just the courts.

The lawsuit further says Banks met with the Nevada Gaming Control Board and told regulators that a report about the scheme had been altered, with key facts removed. Resorts World denies wrongdoing.

A company representative told local media the lawsuit is frivolous and that Resorts World strongly denies the allegations and characterizations. The casino says it will address the claims in the proper forum and has no further comment.

Expert analysis: what this means for poker and casino operations

This case matters because it highlights a central tension in the gaming business: revenue growth versus compliance discipline. Casinos are built to attract action, extend credit, and keep premium players happy. But once those incentives start overpowering risk controls, the entire operation becomes vulnerable.

For the industry, the lesson is clear. Regulators are watching how properties handle:

• third-party payments;
• source-of-funds verification;
• suspicious activity reports;
• player coaching and coordinated betting;
• credit collection and marker exposure.

That applies to more than just big Strip casinos. It also affects poker rooms, live tournaments, VIP programs, and any environment where cash, credit, and repeat action intersect. The cleaner the controls, the safer the ecosystem becomes for honest players.

For players, there is also a strategic takeaway. In a highly regulated market, a strong operator is one that can move quickly, document decisions, and avoid letting short-term revenue override policy. That is especially relevant for anyone who works with poker school content, teaches bankroll management, or manages player-facing services.

If this case develops the way previous Nevada AML cases have, it could push more casinos to tighten internal reviews, escalate suspicious behavior faster, and treat compliance staff as a core part of the business rather than a back-office function.

Resorts World’s AML history and the bigger industry picture

This is not the first time Resorts World Las Vegas has faced scrutiny over suspicious gamblers. In March 2025, the Nevada Gaming Control Board fined the casino $10.5 million for AML violations, the second-largest levy ever imposed on a casino in state history.

That penalty followed an August 2024 complaint alleging unsuitable operations, including allowing illegal bookmakers Mathew Bowyer and Damien LeForbes to wager large sums at the property.

The commission said the casino had an overall lack of control and a culture in which suspicious or illegal activity was, at minimum, negligently disregarded and, at worst, willfully ignored for financial gain. The findings also pointed to the pressure on Resorts World to generate revenue and the fact that executive bonuses were tied to the property’s financial success.

LeForbes later pleaded guilty to federal money-laundering charges and operating an illegal gambling business. In May, the Nevada Gaming Commission placed Bowyer in the state’s black book, banning him from all casinos in Nevada.

For poker players and industry professionals, the broader message is hard to miss. In today’s market, reputation, compliance, and auditability matter just as much as traffic, promotions, or even the best promotions & bonuses. Casinos that ignore that reality risk fines, lawsuits, and long-term damage to player trust.

Conclusion: a compliance case with industry-wide consequences

Preston Banks’ lawsuit may become a key reference point in the ongoing debate over how casinos handle AML risk and whistleblower complaints. If his claims are substantiated, the case could reinforce the idea that internal warnings must be escalated, documented, and protected — not punished.

For the poker world, the story is a reminder that the health of the ecosystem depends on invisible systems as much as visible action. The table matters, but so do the controls behind it.
